Lake Huron's Chinook salmon fishery will likely never return to its glory days because the lake can no longer support the predatory fish's main food source, the herring-like alewife, according to a new University of Michigan-led computer-modeling study.

Researchers at the University of Michigan and Michigan State University have been awarded $3.65 million from the federal government to continue the study of climate change adaptation and climate variability in the Great Lakes region for another five years.

Extreme water-level fluctuations in the Great Lakes, including historic lows on lakes Michigan and Huron in 2013 and substantial upward trends in 2014, are creating serious challenges for many shoreline property owners, tourism-related businesses, municipal planners and others.

Intense rainstorms, floods and heat waves will become more common in the Great Lakes region due to climate change in the coming decades, and ice-cover declines will lengthen the commercial navigation season on the lakes, according to a new summary report released Tuesday.

The recent Arctic blast that gripped much of the nation will likely contribute to a healthy rise in Great Lakes water levels in 2014, new research shows. But the processes responsible for that welcome outcome are not as simple and straightforward as one might think.

The Great Lakes provide a unique educational opportunity to students and residents of all ages. Two new tools from Michigan Sea Grant help bridge that connection: Teaching Great Lakes Science and Great Lakes FieldScope.
